When I plug my custom cable into the CTRL, the lights go very bright and then dim down immediately. Anyone know the reason behind this and if there is a fix?
BigOunceI've got 4 boards and two of them suffer the same issue with the stock cables. I reckon it's the voltage controller in the firmware being initialized.
BigOuncebest shot would be to submit a support ticket. I don't unplug my boards very often so it doesn't affect me. If you really want to get fancy you can pull up the QMK source code and optimize it for startup, but you'd have to spend some time coding in C to make that happen
